Changing Nature' - Dinosaurs
On the surface, Dinosaurs seems like an average sitcom about a working-class dad named Earl Sinclair, his wife, Frannie, and their three kids. The Sinclairs have a lot in common with the Simpsons, other than the fact that they're prehistoric reptiles created by the Jim Henson Company. Yeah … Dinosaurs was a weird show, but it had a devoted following that kept it on the air for 65 episodes. Dinosaurs did delve into social messages, but always maintained such a fun, uplifting tone that looking back, you almost forget that the show ended with the entire family dying a grisly, cold, heartbreaking death.
In the series finale, "Changing Nature," an ice age kicks off. To add some salt in the wound, it's shown that the worldwide climate catastrophe is Earl's fault — or, well, the fault of Earl's company. Once snowflakes starts falling, you know it's all over. The episode closes with the Sinclair family huddled together during the blizzard, figuring that hey, "Dinosaurs have been on this Earth for 150 million years and, it's not like we're gonna just disappear, right?"
Cue tears, wailing, sobbing. It's a depressing ending, but as the AV Club points out, it's an incredibly effective one: "Changing Nature" has a stirring impact, and absolutely sells its message about the dangers of environmental irresponsibility. Still, it's sad to know that Baby Dinosaur will never go to first grade.
'The Boogieman' - Quantum Leap
When Scott Bakula's Dr. Sam Beckett got trapped leaping through time, it made for one of the most cleverly constructed "feel-good" shows of all time. Seriously, that memorable theme song could make even the hardest person crack a smile. Every episode, Sam jumped into a new person's body, in a different period in the 20th century, in order to "put right what once went wrong." Once the historical catastrophe was averted, he'd leap into a new person, say his famous "Oh boy" catchphrase, and begin the next adventure. Along the way, he was aided by his best friend, Al, a hologram from the future.
Due to its time travel format, Quantum Leap jumped freely between many genres, but it was always family friendly. Well, except for the one haunted house episode which gave all the younger viewers nightmares. According to Popoptiq, the episode was titled "The Boogieman." After leaping into the body of a horror novelist, Sam is surrounded by weird supernatural occurrences and is unable to prevent people from dying all around him. To top off all the B-horror movie madness, it's revealed that Sam's holographic buddy Al has been possessed by the Devil — yes, Satan himself — who then tries to murder Sam. It gets intense, but don't worry. Because it's Quantum Leap, things turn out okay in the end, and the show even throws in a fun Stephen King reference.
'Into that Good Night' - Roseanne
he extinction of the Dinosaurs was probably the most depressing finale ever, but Roseanne's downer ending comes pretty close. The heart of Roseanne was always the working-class relationship between the title character and her husband, as they struggled to pay bills, raise a family, and get by. Until the final season, according to Uproxx, where a surprise lottery win turns the family into millionaires, thereby leading to a bizarre 22-episode run of wealthy celebrity hijinks. That's weird enough, but then, the series finale hits viewers with the biggest plot twist of the series: The whole last season was a novel written by Roseanne, who never won the lottery at all.
Hold on tight because it gets worse. Apparently, Roseanne's new fiction writing habit is her way of coping with the loss of her beloved husband, Dan, who actually died of a heart attack in the previous season. Everything that's happened since Dan's death is just a dream. So in about two minutes, the entire run of show goes from comedy to tragedy.
For what it's worth, the 2018 Roseanne revival shows Dan to still be alive, according to Screen Rant. However, even if this new alternate reality ends a lot more happily for one of TV's most popular couples, the original Roseanne ending was still a heartbreaker.
'Over the Edge' - Batman: The Animated Series
Hey, there's a reason he's called the "Dark" Knight. Though all the kids loved Batman: The Animated Series, what made the show a classic was its courageous exploration of mature themes like trauma, loss, abuse, identity crises, and more. However, the show's most intense episode was "Over the Edge," which shows a horrific implosion in the relationship between Batman and his eternal ally, Commissioner James Gordon. The fallout occurs when Gordon's daughter, Barbara, is killed by the Scarecrow. As she dies in her father's arms — a long, horrible moment that viewers are forced to observe — Gordon blames Batman and swears to destroy everything the Dark Knight stands for.
It's thrilling, but painful to watch. Sure, the Joker's a scary guy, but even his machinations can't compare to the gut-wrenching sight of Jim Gordon raiding the Batcave and blowing up the Batmobile. As written by the AV Club, the episode is eventually revealed to be a dream sequence experienced by Barbara, who is still alive. Nonetheless, mainstream superhero cartoons don't get much darker than this.
'Stevil' - Family Matters
Okay, so nothing turns a wholesome family sitcom into a terrifying creepshow like a good Halloween episode. However, the "Stevil" episode of Family Matters is horrifying enough that Freddy Krueger would probably run away, crying into his claws.
As described by Decider, "Stevil" is the name of a demonically possessed ventriloquist dummy who just happens to look exactly like Urkel, the show's nerdy star character. Now, ventriloquist dummies are already creepy. Just ask the generation of kids who grew up with The Twilight Zone. But this evil Urkel doll is like something crafted in the bowels of Hell. Stevil's Wishmaster-esque voice would be enough to make countless children hide under the bed, and after he comes to life, the dummy proceeds to systematically torture, play with, and murder the entire cast of the show. So yes, for one episode, Family Matters literally turned into a slasher movie.
Sure, sure, it ends up being a dream sequence, and these episodes always get retconned. But hey, try telling that to the traumatized young Urkel fan who will now refuse to wear suspenders, ever again. You can't just shout "dreaming!" after every horrifying episode and have it be fine.
